Visual and aural are two most important channels of information processing. While most of the interaction with computers have been designed around the visual channel, there are circumstances where voice based man-machine interaction becomes preferable, and in some cases, necessary, given that voice based interaction comes naturally to humans and can be used by illiterate people *** userinterfaces (VUIs), however, are linear and non-persistent, thus have serious implications on the working memory load [10, 11]. Compared to a visual interface, VUIs (considering Interactive Voice Response system) is slow as access is sequential, rather than random. Moreover, however robust a Speech Recognition (SR) platform may be, it can never achieve 100% accuracy. This results in an error prone interaction. In addition, speech interaction may require higher user attention, and take a longer time to complete tasks, as compared to using Graphical userinterface (GUI).The significant work has been done for improvement of IVR systems still the technology has not been exploited to its fullest. Most of the work proposes solution which is common to all [13, 14, 15]. However we know that every individual has a different knowledge, skill and literacy level. A human operator is still good at handling the people with different properties and is therefore usually preferred over IVR [12].On other hand, GUIs require both mental as well as physical attention. The user would not be able to use the GUI when hands and/or visual channel are busy with other *** this paper, we focus upon the performance of two types of interfaces named VUI (SR based) and GUI, and relate the results with the user's level of *** conducted a 2X2 study, comprising of two goals, of two groups of participants---semi-literate (class 7th to class 11th pass) and literate (undergraduates to PhD students).

Today's enterprise web applications demand very high release cycles - and consequently, frequent tests. Automating these tests typically requires a behavior model: A description of the states the application can be in, the transitions between these states, and the expected results. Furthermore one needs scripts to make the abstract actions (transitions) in the model executable. As specifying such behavior models and writing the necessary scripts manually is a hard task, a possible alternative could be to extract them from existing applications. However, mining such models can be a challenge, in particular because one needs to know when two states are equivalent, as well as how to reach that state. We present ProCrawl (Process Crawler), a generic approach to mine behavior models from (multi-user) enterprise web applications. ProCrawl observes the behavior of the application through its userinterface, generates and executes tests to explore unobserved behavior. In our evaluation of three non-trivial web applications (an open-source shop system, an SAP product compliance application, and an open-source conference manager), ProCrawl produces models that precisely abstract application behavior and which can be directly used for effective model-based regression testing.

Socially coupled systems are comprised of interdependent social, organizational, economic, infrastructure and physical networks. Today's urban regions serve as an excellent example of such systems. People and institutions confront the implications of the increasing scale of information becoming available due to a combination of advances in pervasive computing, data acquisition systems as well as high performance computing. Integrated modeling and decision making environments are necessary to support planning, analysis and counter factual experiments to study these complex systems. Here, we describe SIMFRASTRUCTURE - a flexible coordination middleware that supports high performance computing oriented decision and analytics environments to study socially coupled systems. Simfrastructure provides a multiplexing mechanism by which simple and intuitive user-interfaces can be plugged in as front-end systems, and high-end computing resources can be plugged in as back-end systems for execution. This makes the computational complexity of the simulations completely transparent to the users. The decoupling of userinterfaces and data repository from simulation execution allows users to access simulation results asynchronously and enables them to add new datasets and simulation models dynamically. Simfrastructure enables implementation of a simple yet powerful modeling environment with built-in analytics-as-a-service platform, which provides seamless access to high end computational resources, through an intuitive interface for studying socially coupled systems. We illustrate the applicability of Simfrastructure in the context of an integrated modeling environment to study public health epidemiology.
